Never fear! B3N is here! (In other words I will be answering this). Also thought I might point out that you have 3 pokemon weak to Ice, to pokemon weak to Fire, 2 pokemon weak to Ground, and 2 pokemon weak to Fighting. It might be a little while seeing as I am trying to fix the synergy.

@B3N: but considering the three types that benefit from Sandstorm are Rock, Ground, and Steel....that's kind of a given. that's like spoinks trolling self pointing out on a MonoWater team that it has a glaring Grass and Electric weakness xD

Okay? I realize that, but either way he still has a slew of weaknesses. It is quite possible to create a sand team that doesn't have an insane amount of stacked weaknesses. I just noticed that this team also has 4 Pokemon weak to water. It's a good team, it just needs help with synergy. TBH I could care less what types benefit from sandstorm, too many stacked weaknesses is not a good thing.
